Package net.sf.saxon.trace Description
</H2>
<P>
<p>This package provides an interface to Saxon tracing and debugging capabilities.</p>
<p>The package was originally created by Edwin Glaser.</p>
<p>The package includes three tracing modules that can be optionally selected:
<code>XSLTTraceListener</code>, <code>XQueryTraceListener</code>, and
<code>TimedTraceListener</code>. These all receive notification of the same events,
but select and format the events in different ways to meet different requirements.
Other events are notified through the <code>TraceListener</code> interface that
are ignored by tracing applications, but may be of interest to debuggers.</p>
